I want to do something like this:

local text = "/texthere\"

but it errors with "unfinished string", because the \ skips the next ". How do I fix this?

Escape the backslash with another backslash.

local text="/texthere\\"

Thanks!

local text = string.char(47).."texthere"..string.char(92)

Well, that's adventurous ! The slash doesn't need to be escaped, only the backslash, but it's an acceptable solution.

Old habits die hard (VB6)!

Are those numbers the same as the ones you get from os.pullEvent("char")?

"char" just returns strings, if I remember correctly. Do you, perchance, mean os.pullEvent("key") ?

If you were to wrap the result in a string.byte(), yes. If, as Dog said, you meant os.pullEvent("key"), no. The numbers returned by the key event are key codes.

[Inksaver]

The numbers are the decimal equivalent of the ASCII system.

I had to use them a lot with VB6

string.char(X) is the same as Chr$(X) in VB
"\" has the ASCII code of 97

no one is going to mention this?

local text = [[/text here\]]

That's definitely the most elegant solution!
